FIELD OF THE INVENTION

This invention is in the field of medicinal chemistry and relates tocompounds, and pharmaceutical compositions thereof, that inhibitbacterial gyrase and Topo IV. The compounds are useful as inhibitors ofbacterial gyrase and Topo IV activity. The present invention alsorelates to methods of using the compounds of this invention for treatingresistant bacterial infections in patients. The present invention alsorelates to treating resistant bacterial infections in patients usingcompounds of the present invention in combination with one or moreadditional antibacterial agents and/or one or more additionaltherapeutic agents that increase the susceptibility of bacterialorganisms to antibiotics.

BACKGROUND OF THE INVENTION

Bacterial resistance to antibiotics has long been recognized, and it istoday considered to be a serious worldwide health problem. As a resultof resistance, some bacterial infections are either difficult to treatwith antibiotics or even untreatable. This problem has become especiallyserious with the recent development of multiple drug resistance incertain strains of bacteria, such as Streptococcus pneumoniae (SP),Mycobacterium tuberculosis, and Enterococcus. The appearance ofvancomycin resistant enterococcus was particularly alarming becausevancomycin was formerly the only effective antibiotic for treating thisinfection, and had been considered for many infections to be the drug of“last resort”. While many other drug-resistant bacteria do not causelife-threatening disease, such as enterococci, there is the fear thatthe genes which induce resistance might spread to more deadly organismssuch as Staphylococcus aureus, where methicillin resistance is alreadyprevalent (De Clerq, et al., Current Opinion in Anti-infectiveInvestigational Drugs, 1999, 1, 1; Levy, “The Challenge of AntibioticResistance”, Scientific American, March, 1998).

Another concern is how quickly antibiotic resistance can spread. Forexample, until the 1960's SP was universally sensitive to penicillin,and in 1987 only 0.02% of the SP strains in the U.S. were resistant.However, by 1995 it was reported that SP resistance to penicillin wasabout seven percent and as high as 30% in some parts of the U.S. (Lewis,FDA Consumer magazine (September, 1995); Gershman in The MedicalReporter, 1997).

Hospitals, in particular, serve as centers for the formation andtransmission of drug-resistant organisms. Infections occurring inhospitals, known as nosocomial infections, are becoming an increasinglyserious problem. Of the two million Americans infected in hospitals eachyear, more than half of these infections resist at least one antibiotic.The Center for Disease Control reported that in 1992, over 13,000hospital patients died of bacterial infections that were resistant toantibiotic treatment (Lewis, “The Rise of Antibiotic-ResistantInfections”, FDA Consumer magazine, September, 1995).

As a result of the need to combat drug-resistant bacteria and theincreasing failure of the available drugs, there has been a resurgentinterest in discovering new antibiotics. One attractive strategy fordeveloping new antibiotics is to inhibit DNA gyrase, a bacterial enzymenecessary for DNA replication, and therefore, necessary for bacterialcell growth and division. Gyrase activity is also associated with eventsin DNA transcription, repair and recombination.

Gyrase is one of the topoisomerases, a group of enzymes which catalyzethe interconversion of topological isomers of DNA (see generally,Kornberg and Baker, DNA Replication, 2d Ed., Chapter 12, 1992, W.H.Freeman and Co.; Drlica, Molecular Microbiology, 1992, 6, 425; Drlicaand Zhao, Microbiology and Molecular Biology Reviews, 1997, 61, 377).Gyrase itself controls DNA supercoiling and relieves topological stressthat occurs when the DNA strands of a parental duplex are untwistedduring the replication process. Gyrase also catalyzes the conversion ofrelaxed, closed circular duplex DNA to a negatively superhelical formwhich is more favorable for recombination. The mechanism of thesupercoiling reaction involves the wrapping of gyrase around a region ofthe DNA, double strand breaking in that region, passing a second regionof the DNA through the break, and rejoining the broken strands. Such acleavage mechanism is characteristic of a type II topoisomerase. Thesupercoiling reaction is driven by the binding of ATP to gyrase. The ATPis then hydrolyzed during the reaction. This ATP binding and subsequenthydrolysis cause conformational changes in the DNA-bound gyrase that arenecessary for its activity. It has also been found that the level of DNAsupercoiling (or relaxation) is dependent on the ATP/ADP ratio. In theabsence of ATP, gyrase is only capable of relaxing supercoiled DNA.

Bacterial DNA gyrase is a 400 kilodalton protein tetramer consisting oftwo A (GyrA) and two B subunits (GyrB). Binding and cleavage of the DNAis associated with GyrA, whereas ATP is bound and hydrolyzed by the GyrBprotein. GyrB consists of an amino-terminal domain which has the ATPaseactivity, and a carboxy-terminal domain which interacts with GyrA andDNA. By contrast, eukaryotic type II topoisomerases are homodimers thatcan relax negative and positive supercoils, but cannot introducenegative supercoils. Ideally, an antibiotic based on the inhibition ofbacterial DNA gyrase would be selective for this enzyme and berelatively inactive against the eukaryotic type II topoisomerases.

The widely used quinolone antibiotics inhibit bacterial DNA gyrase.Examples of the quinolones include the early compounds such as nalidixicacid and oxolinic acid, as well as the later, more potentfluoroquinolones such as norfloxacin, ciprofloxacin, and trovafloxacin.These compounds bind to GyrA and stabilize the cleaved complex, thusinhibiting overall gyrase function, leading to cell death. However, drugresistance has also been recognized as a problem for this class ofcompounds (WHO Report, “Use of Quinolones in Food Animals and PotentialImpact on Human Health”, 1998). With the quinolones, as with otherclasses of antibiotics, bacteria exposed to earlier compounds oftenquickly develop cross-resistance to more potent compounds in the sameclass.

There are fewer known inhibitors that bind to GyrB. Examples include thecoumarins, novobiocin and coumermycin A1, cyclothialidine, cinodine, andclerocidin. The coumarins have been shown to bind to GyrB very tightly.For example, novobiocin makes a network of hydrogen bonds with theprotein and several hydrophobic contacts. While novobiocin and ATP doappear to bind within the ATP binding site, there is minimal overlap inthe bound orientation of the two compounds. The overlapping portions arethe sugar unit of novobiocin and the ATP adenine (Maxwell, Trends inMicrobiology, 1997, 5, 102).

For coumarin-resistant bacteria, the most prevalent point mutation is ata surface arginine residue that binds to the carbonyl of the coumarinring (Arg136 in E. coli GyrB). While enzymes with this mutation showlower supercoiling and ATPase activity, they are also less sensitive toinhibition by coumarin drugs (Maxwell, Mol. Microbiol., 1993, 9, 681).

Despite being potent inhibitors of gyrase supercoiling, the coumarinshave not been widely used as antibiotics. They are generally notsuitable due to their low permeability in bacteria, eukaryotic toxicity,and poor water solubility (Maxwell, Trends in Microbiology, 1997, 5,102). It would be desirable to have a new, effective GyrB inhibitor thatovercomes these drawbacks. Such an inhibitor would be an attractiveantibiotic candidate, without a history of resistance problems thatplague other classes of antibiotics.

Replication fork movement along circular DNA can generate topologicalchanges both ahead of the replication complex as well as behind in thealready replicated regions (Champoux, J. J., Annu. Rev. Biochem., 2001,70, 369-413). While DNA gyrase can introduce negative supercoils tocompensate for the topological stresses ahead of the replication fork,some overwinding can diffuse back into the already replicated region ofDNA resulting in precatenanes. If not removed, the presence of theprecatenanes can result in interlinked (catenated) daughter molecules atthe end of replication. TopoIV is responsible for separating thecatenated daughter plasmids as well as removal of precatenanes formedduring replication ultimately allowing for segragation of the daughtermolecules into daughter cells. Topo IV is composed of two ParC and 2parE subunits as a C2E2 tetramer (where the C and E monomers arehomologuous to the A and B monomers of gyrase, respectively) thatrequires ATP hydrolysis (at the N-terminus of the E subunit) to resetthe enzyme to re-enter the catalytic cycle. Topo IV is highly conservedamong bacteria and is essential for bacterial replication (Drlica andZhao, Microbiol. Mol. Biol. Rev., 1997, 61, 377).

While little attention has been paid to inhibitors that target ParE ofTopoIV, the action of the newer quinolones on the ParC region has beenwidely studied (Hooper, D. C., Clin. Infect. Dis., 2000, 31(Suppl 2):S24-28). It has been demonstrated that moxifloxacin and gatifloxacinhave more balanced activities against Gyrase and TopoIV resulting inexpanded Gram positive coverage as well as lower levels of resistancecaused primary-target mutation. In those cases, susceptibility islimited by the sensitivity of the second target to the antibacterialagent. Thus, agents that can effectively inhibit multiple essentialtargets can result in an expanded spectrum of potencies, improvedantibacterial potencies, improved potency against single target mutants,and/or lower spontaneous rates of resistance.

As bacterial resistance to antibiotics has become an important publichealth problem, there is a continuing need to develop newer and morepotent antibiotics. More particularly, there is a need for antibioticsthat represent a new class of compounds not previously used to treatbacterial infection. Such compounds would be particularly useful intreating nosocomial infections in hospitals where the formation andtransmission of resistant bacteria are becoming increasingly prevalent.

Scheme I above shows a general method for preparingN′-alkyl-N-cyanoureas 3 useful in the preparation of the compounds ofthe present invention wherein Z is NH. At step (a), cyanamide 2 wastreated with an alkyl isocyanate in aqueous sodium hydroxide to afford,after acidification, compound 3. One of skill in the art would recognizethat a variety of alkyl isocyanates would be amenable to the reactionconditions of Scheme I to form a variety of N′-alkyl-N-cyanoureas.

Scheme II above shows a general method for preparing the benzimidazolecompounds of the present invention wherein Z is NH or 0. Thebromo-aniline 4 was treated with sodium perborate and acetic acid toform the difluoro-nitro compound 5. Compound 5 was treated with Ring Ain the presence of sodium hydride to afford the bi-aryl compound 6. Theremaining fluoro group of compound 6 was displaced with ammonia to formthe amino compound 7. The 2-nitro-5-bromoaniline 7 was then coupled toan aryl boronic acid, at step (d), in the presence of palladium to formthe tri-aryl compound 8. The nitro group of compound 8 was reduced toform a diamino compound which was either treated with anN′-alkyl-N-cyanourea 3 or with anN,N-dialkylureamido-2-methyl-2-thiopseudourea 3a to form a benzimidazolecompound of formula I wherein Z is NH 9.

Alternatively, intermediate 8 may be used to form compounds of formula Iwherein Z is O. Compound 10 was formed by treating 8, after reduction tothe diamino compound, with 2-methyl-2-thiopseudourea andR²-chloroformate according to the method described by L. I. Kruse et al,J. Med. Chem. 1989, 32, 409-417. One of ordinary skill in the art wouldrecognize that the reactions depicted in Scheme II above are amenable toa variety of R¹ and Ring A groups of the present invention.

In an alternative method, intermediate 8 was treated with eitherN,N-diethlycarboxy-2-methyl-2-thiopseudourea orN,N-diethlyureamido-2-methyl-2-thiopseudourea to form compounds 10 and9, respectively. The syntheses of bothN,N-diethlycarboxy-2-methyl-2-thiopseudourea andN,N-diethlyureamido-2-methyl-2-thiopseudourea are described in theExamples set forth infra.

Scheme III above shows a general method for preparing compounds offormula II-a using methods substantially similar to those described byKiyomori, A.; Marcoux, J.-F.; Buchwald, S. L., Tetrahedron Letters, vol.40, (1999) 2657-2660. Compound 7 was treated with diboronic ester in thepresence of Pd(dppf)/potassium acetate in DMSO at 80° C. to affordintermediate 11. Compound 11 was treated with 4-C(O)N(R′)₂-imidazole inthe presence of copper acetate to form the 4-C(O)N(R′)₂-imidazol-1-ylcompound 12. Compounds of formula II-a were prepared from compound 12 asdescribed in Scheme II, steps (e), (f), and (g).

Although 4-C(O)N(R′)₂-imidazole was used to exemplify, one of ordinaryskill in the art would recognize that a variety of R¹ groups areamenable to the displacement reaction at step (c) to form a variety ofcompounds of the present invention. Generally, the boronate intermediate11 may be treated with a variety of R¹-halides or R¹-triflates, usingmethods well known to one of ordinary skill in the art, to formintermediate compounds 12′ as shown below. Using the methods recitedherein and those known to one of ordinary skill in the art, compounds12′ are useful for preparing compounds 9 and 10 of the present inventionas depicted above at Scheme II.

Scheme IV above shows an alternate method for preparing compounds offormula II-a. Compound 13 was nitrated to form 14. Compound 14 wastreated with ammonium hydroxide to form the amino compound 15. The bromogroup of compound 15 was treated with the BrZn-Ring A reagent in thepresence of Pd(PPh₃)₄ in THF to form compound 16. Compound 16 wastreated with the 4-C(O)N(R′)₂-imidazole in the presence of sodiumcarbonate to form the 4-C(O)N(R′)₂-imidazol-1-yl compound 18. Compoundsof formula II-a were then prepared from compound 18 as described inScheme II, steps (e), (f), and (g).

Scheme V above shows a general method for preparing compounds of formulaVII. Compound 19 (puchased commercially from CB Research) underwentSuzuki-type coupling with commmercial reagents (purchased from Aldrichor Manchester Organics Limited) of type 20 to form intermediate 21.Compound 21 was brominated with bromine in acetic acid to form bromide22, then nitrated with nitric acid in the presence of TFA and TFAA toform intermediate 23. Acidic hydrolysis of compound 23 provided aniline24. The bromo group of compound 24 was converted into boronate ester 25in the presence of Pd(PPh₃)₄ in buffered dioxane. Compound 25 underwentSuzuki-type coupling with intermediate 26 (prepared from thedi-bromoheteroaryl ring D [commercially available from Aldrich, etc.]according to the procedure of Wang, X. et al., Tetrahedron Letters, vol.41, (2000) 4335-4338) to prepare nitro aniline intermediate 27.Raney-nickel reduction of the nitro group in compound 27, followed bytreatment with N,N-dialkylureamido-2-methyl-2-thiopseudourea 3a affordedbenzimidazole compounds of formula VII.
